IMPROVEMENT IN DISTILLING PETROLEUM.

Specification forming part of Letters Patent No. 56,276, dated July 10, 1866.

To all whom it may concern:

Be it known that we, WILLIAM H. SANG- s'rE t and THEODORE O. SPENcER, of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Impro vements in Petroleum-Stills; and we do hereby declare that the following is a clear and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. The nature of our invention consists in dispensing with thecondensing-worm or its equivalent now in common use for condensing the vapor of petroleum during the process of dis-' tilling, and so constructing and arranging the still that the vapor is brought directly in contact with a moving body of cold water, through which it rises to the top of the tank made to receive it.

To enable others skilled in the art to make and use our invention, we will proceed to de scribe its construction and operation.

We construct our still in the usual form and of cast-iron, as being the cheapest material although some prefer sheet metal, iron, or cop per. The tank into which the vapor is forced and condensed we construct of wood. It is held together by iron hoops in the usual way.

In the drawings, Figure 1 represents a side elevation of the still, and Fig. 2 a vertical section through the tank.

A represents what is commonly called the goose-neck. O is a tube which connects with it and passes down and into the tank, terminating at D, as shown.

It is operated as follows: The tank, Fig. 2, is filled with water from the faucet B, which is kept in motion by the faucet E being turned so that it can run oif as fast as poured in from faucet B. During the process of distilling the vapor is forced into the water at the point D, and is immediately condensed into liquid, which rises to the surface and is drawn oh"? by a faucet or other suitable device.

By this arrangement we claim a cheaper and quicker method of condensing and cooling the vapor of petroleum.

What we claim as our invention, and desire to secure by Letters Patent, is

1. The combination of the tank, Fig. 2, or its equivalent, the tube 0, and faucet E, with a still for distilling petroleum, when constructed as and for the purposes herein substantially set forth.

2. The method herein described of condensing the vapor of petroleum by passing it directly through water.
